Kinect Hacked For 3-D Scanning Of Archaeology Site
BY Kit EatonToday
University of California, San Diego students will be going to Jordan soon to take part in an archaeological dig that's decidely futuristic: As they uncover artifacts and structures in the soil, they'll be using high-quality 3-D scanning to record accurate positional details--rich data that could be incredibly useful in the future. Instead of using expensive and complex imaging systems like LIDAR, however, the team will use a hacked Microsoft Kinect to do the job for them.
It's actually using a system developed by the California Institute for Telecommunications and IT (Calit2), which taps directly into Kinect's streaming data feed that's a blend of 3-D positional data (achieved by projecting bright, invisible spots of infrared light onto objects and then observing them with an IR camera) and color video images. The Calit2 team has perfected this system so it's useful for making fast and accurate 3-D scans of objects that can then be inserted into a virtual world like Second Life--the trick is to correctly register all the images recorded of the object so they match up next to each other properly as you wave the Kinect around. Thus far the Calit Kinect hack uses an overhead video tracking device to do this, which limits it for indoor use--a tweak is already planned to let it work in an outdoors settings, however, and its inventor thinks it could even be used to scan whole buildings (at which point Google, with its penchant for doing this inaccurately for its Street View system, may get interested).
